Howdy fellow user!
The envelope of a virus is made of a lipid bilayer derived from the host during the budding stage, basically the exiting stage of a newly made virus particle.
Let's do a little rewind.
The virus infects the cell to make many copies of itself by using the transcription and translational machinery available there. The virus proteins are translated first. Some of them are envelope proteins that get collected on the surface of the cell in a designated spot so when the virus buds off, it takes the bilayer with the accumulated envelope proteins.
Hope you found this response useful! 😄

∙ 15y agoThe envelope comes from the cells that the virus infects. When the virus is assembled inside the infected cells, it is released either by budding from the cell membrane or by cell lysis. The membrane can come from the plasma membrane, the golgi, or one virus uses the nuclear membrane (I forgot which one).

∙ 14y agoDo you mean "what PART of the cell akes up the viral envelope"? Then the answer is: the cell membrane. Viri themselves do not have cells, they use the cells of the organisms they infect as machines and for parts to self-replicate.

∙ 13y agoThe viral envelope is derived from the host's plasma membrane, although some of the molecules of this membrane are specified by viral genes. Viral glycoproteins on the outer surface of the envelope bind to specific receptors on the surface of a host cell.
Wiki User
∙ 13y agoA viral envelope contains glycoproteins that help the virus identify receptors through which it may enter thus helping it to bind to a cell. It also offers protection from environmental factors such as heat

What structure of a bacterial cell determines which kind of biological stain it will take up?
The cell wall of gram-negative bacteria is a thin layer sandwiched between an outer cell envelope and an inner cell membrane. The gram-positive cell wall is much thicker, has no cell envelope, and contains additional substances that retain the blue stain.
What action do viruses take when they enter the body' cell?
it poops on itself :(
Why are Viruses not considered living by most Biologist?
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.

If you take a virus apart would you find cells?
Viruses are not made of cells. They are not cells. They are DNA or RNA with a protein coat.Viruses are not made of cells. Only living organisms are made of cells. Viruses are considered infectious particles. Viruses are in fact composed of a protein capsid encapsulating genetic material (DNA or RNA). In some instances, an outer envelope may be present. Additional structures such as tail fibres and a base plate, etc may also be present in some viruses, such as the T3 bacteriophage.
Do all viruses have an envelope?
No. I don't think so.
What is uses energy to take particles into a cell?
viruses
What surrounds a virus?
I take it that you meant to ask what surrounds the genome of the virus. The genome of the virus (be it DNA or RNA) is enclosed within the capsid shell. The capsid shell is made by the oligomerisation of capsid proteins in a specific organised manner. The genome together with the capsid is termed as nucleocapsid. Sometimes the nucleocapsid is surrounded by a phospholipid membrane (of host origin) called the envelope. The viruses which have an envelope are called envelope viruses eg., Chikunguyna virus, Rabies virus, HIV and the viruses without an envelope are called naked viruses eg., Poliovirus, Rotavirus
What do viruses need to carry on?
Viruses need a host cell to be able to multiply. Once they get attached to the cell membrane or cell wall of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
What are Viruses that immediately take over a cell's functions called?
A virus the immediately takes over a cell's functions is an active virus. An active virus causes the host cell to make new viruses, destroying the host cell.
What circumstances can viruses reproduce?
Only within a living cell that they can take control of.
Do Viruses multiply through binary fission?
No, they do not. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again.No, only living cells divide by binary fission. Viruses are not alive.
What do Golgi complex do in an animal cell?
they take the poos for the cell.
What is the life cycle of a virus called?
A virus is RNA and DNA surrounded by protein. A virus can not live alone without a host cell. The life cycles are: attachment, penetration, uncoating, replication and release. During the release process, viruses may escape from the host cell by causing cell rupture viruses typically "bud" from the host cell. During the budding process, a virus acquires the phospholipid envelope containing the embedded viral glycoproteins.
Do viruses break into bodies cells to reproduce?
Yes, that's basically what they do: they take over the cell's own ability to reproduce itself but then not to make more of that cell but to make more viruses.
How does a virus different from a living cell?
viruses do not grow, take in food, or make waste living cell make waste, take in food, grow
